ASTM B111 / ASME SB111 C68700 O61 ALUMINIUM BRASS SMLS TUBE FOR CONDENSER

Overview

Aluminum Brass Tube is a copper zinc alloy containing aluminum and small amount of arseric which is added as an inhibitor against dezincification. Inhibited Aluminum Brass resists the action of high velocity salt and brackish water and is commonly used for condenser tube. The outstanding characteristic of Aluminum Brass is the high resistance to impringement attack. Aluminum Brass tubes are highly accepted and one of the extensively used material for various industrial applications.

HEAT EXCHANGER AND CONDENSERS COPPER ALLOY TUBES

Admiralty C44300Highly resistant to general corrosion – where pressures, velocities and temperatures are moderate.
Aluminium Brass C68700These tubes are especially adapted to resist corrosion by both salt and brackish waters.
Copper Nickel 90/10 C70600This alloy is highly resistant to corrosion by turbulently flowing sea water indicate it to be an excellent condenser tube alloy for salt water use.
Copper Nickel 80/20 C71000This alloy has intermediate properties between those of 10% and 30% copper nickel. Tubes of this alloy have found widest use in feedwater heaters and evaporators.
Copper Nickel 70/30 C71500Condenser tubes of this alloy are giving long and dependable service at sea. It is also highly satisfactory for tubes in evaporators, condensers, and superheaters.
This alloy is particularly desirable where high temperatures are encountered.
